Patented July 12, 1932 UNITED STATES HER-MANN KAMPES, or EssENgRuHR, GERMANY YIELDING JOINT srnrr ron THRESHOLDS AND SILLS Application filed November 20, 1930, Serial No. 496,931, and in Germany November 18, 1929.

The invention relates to a yielding joint strip for the sill or threshold of sash windows or sash doors. The usual way in which sash windows have hithereto been rendered tight 6 is by rebating the sill or threshold as well as the window sash in steps. Therefore the sill of windows and the threshold of doors present projecting members which are awkward. In the case of hospitals for instance it is of great to importance that the shocks which operation or sick beds on wheels have imparted to them when passing over such obstacles should be avoided.

Hinged doors with a roller shaped sealing IF; batten or rail let into the theshold and arranged between covering strips and actuated by springs are alreadyknown. This arrangement however, possesses the disadvantage, that the roller protrudes above the sill or m threshold surface when the door is open; moreover, such a roller could only then fulfill its purpose of a perfect sealing if it could be brought into an efiective and accurate contact with the bottom edge of the door, which is practically impossible; then there is the further disadvantage, that the roller must protrude above the threshold and that it is awkward and easy to miss ones footing over it.

The purpose of the invention is to create a sealing off of draught and so on by inserting two covering rails into the sill or weatherboard or' threshold, a slot being formed between them into which a strip protudes, a

: preferably T-shaped rail, acted upon by a spring closing the slot when the window or door is open, but is in close contact with the strip on its whole length when the window or door is closed.

With this and other objects in view the invention consists in certain novel features of construction, combination and arrangements of parts, which will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawing: Fig. 1 is a vertical cross section of the lower part of a sash door and Fig. 2 is a corresponding illustration of a sash window.

Fig. 3 is a vertical longitudinal section through the device at two different positions of the lower sash, whereas F Fig. 4c shows a'section according to 44 of The sash door according to Fig. 1 consists of three sashes which can slide in the same manner as sash windows in the guides a a a the sashes b and b beingshown. A batten 70 is provided on the outside of the lower sash b along its lower edge and projects somewhat towards the bottom. A rail or strip- 0 is fixedly attached to the lower rail of the lower sash 6 The threshold or. weatherboard is provided with a recess d which is partially covered by twoparallel rails or stripsxe. The rail 0 is free to protrude into the slot formed between the rails 0, when the sash b is in its extreme lower position. Pieces of pipes f are let into the masonry at several places below the rails e, these pipe pieces being provided at their top with a large slot 7. Within the slot 7. of all the pipe pieces f a preferably T-shaped rail 9 is suitably inserted and guided, it being acted upon by spiral or helical springs h arranged within thepipes' f. The springs h tend to press therail g into'its extreme top position, in which the bridge 9 of the rail 9 seals. off the floor. wards the outside so that the batten is seals the interstice or slit between thethreshold and sash, as regards the outside, when the door is closed.

The device of the'lower sash 2' of the two sashwindowshown in-Fig. 2 resemblesin all its details the above described device. 1

. Ifthe lowersash b ori is pulled down, then itabuts-with its strip c on to the bridge 9 of the rail g, and forcesit downwards, at the same timecompr'essing the springs it into the position shown in Figs. 1 and-2 and in theright hand side o-fFig. 3. The sash can stably remain by its own weight in this position, or maybe locked in this position by means of suitably arrange'dlatches. As soonas the sash b or i is pushed up the rail g follows it until it reaches the extreme upper position shown in the left half of Fig.3, in which position its surface hasreached the The thresholdis step-formed to- 39 level of the floor or sill. The floor or sill has thus no awkward recesses or projecting battens, but notwithstanding this the device forms a perfect seal.

The T-shaped rail 9 may be replaced by a flat rail or strip provided with bolts or the like projecting parts adapted to abut against the rails 6 when the sash or dis raised. 1
